And we are projecting some raster data from Hong Kong 1980 (horizontal) + Hong Kong Principal Datum (vertical) to WGS84 + EGM96 using Project Raster tool. We know we should take "Vertical" checkbox in the tool, and tool automatically suggests "Hong_Kong_1980_To_WGS_1984_1" as horizontal transformation method. But what method should we use for vertical transformation (HKPD to EGM96)? Is there a full list of transformation method we can refer to?&nbsp;</P><P></P><P>Thank you</P></BODY></HTML> Mon, 20 Jan 2020 06:42:45 GMT FeifeiLin 2020-01-20T06:42:45Z How to choose transformation method for vertical spatial reference https://community.esri.com/t5/arcmap-questions/how-to-choose-transformation-method-for-vertical/m-p/242354#M595 <HTML><HEAD></HEAD><BODY><P>We are using ArcGIS Pro 2.4.
